Current consumption house

[tgw-de]

I have two inverters SE5000 and SE3500, a WattNode Windy-3Y-400-MB and an LG battery.
So far I have found almost all the entities and can read out the battery status, feed-in etc.
However, I cannot find the entity for the current consumption of the house. I don't mean the total consumption.
In which entity should this be mapped?
I currently get this value as the last value via the Solaredge API. I have all entities on a dashboard, none of these entities even come close to matching the API value. Shouldn't it also be possible to read this in the Wattnode?

Is there an overview somewhere of which entities are for what?

I have the same issue on a SE10000H, I tried calculating the difference between solar production I1 AC Power in W and the I1.M2 AC Power in W, the result is pretty close to the actual house consumption with some glitches where data are inconsistent with reality and I don't know why yet. The value might not be accessible via Modbus or is well hidden.
